Is there anything special about doing neutral grip pull-ups? What I mean by that is there any added benefit from doing this exercise that differentiates it from regular pull-ups and/or chin-ups. Personally, I only do regular chin-ups and pull-ups so I'm debating if I should try neutral grip.

The more suprinate your wrists are, the stronger your biceps are. The biceps are weakest when using a pronated grip and strongest when using a supianted grip. The "neutral" grip is just somewhere in between. The issue when pulling is that the biceps generally fatigue faster than the lats, so the lats will get a better workout if the biceps last longer. When using a neutral grip, you'll work the lats better than while using a pronated grip, but not as good as while using a supinated grip.
